Title:
Adding second graphics card causes infinite reboot loop for Ubuntu,
but Windows boots.
Status in “xserver-xorg-video-nouveau” package in Ubuntu:
Confirmed
Bug description:
I have a motherboard which is able to use both the integrated graphics
card and a dedicated graphics card at the same time.
The integrated graphics card is an RS880 [Radeon HD 4200] with two
outputs, powered by the foss radeon driver. To this I am trying to add
a PCI-Express NVidia Quadro FX (I think it's a Quadro FX 3450).
Windows 7 boots fine on this configuration and is able to use both
cards concurrently (one monitor attached to each card). However,
Ubuntu enters an infinite reboot loop with this configuration. The
Live USB has the same problem. I was able to boot it into recovery
mode, but was not able to start X from this configuration (lightdm
hangs with a black screen, and 'startx' says my user account is not
authorized).
When I configured my BIOS to use only the Quadro FX without the
integrated card, Ubuntu booted fine using the nouveau driver.
